what gauge wire should i use to connect batterys together for my solar set up?

Answers

When the length of the wire is not more than 2 ft. for the battery connection distance round trip, than 6 or 8 gauge wire will be used. When the solar array connection distance round trip is 20 feet, than 10 gauge wire is needed. If the distance is 30 ft., than 8 gauge wire is needed. If the distance is 40 ft., than 6 gauge wire is needed. It is better to use stranded wire than solid wire.

I HIGHLY do NOT recommend connecting an alternator to this controller! You WILL fry it! It's only designed for a MAXIMUM of 30 amps worth of solar panels, NOT an alternator which puts out double or triple that! If you need to connect to an alternator, you NEED to use a BATTERY ISOLATOR which has the appropriate amp rating for your alternator. You can find them at most marine or automotive supply stores. Just do a web search for Battery Isolators and it should give you many results. I would provide you a link to my recommendation but that's against the rules. Sorry :(

This controller at 30A and rated for a 12V system is more controller than the one 110W panel and one battery needs. (110w divided by 15v (max) = 7.33a) But, since you'll probably be adding panels to supply your needs in the future (and the 'battery' won't run a teevee all evening and a small fridge over night, so you'll need a bank of them), don't skimp now. Get this controller and use 10gauge wire. It's rated at 30 amps, but even with drop, will support three of your panels. I'd suggest you get 2 (4 would be better) golf cart type 6V deep cycle batteries instead of a marine 12v. It's a piece of cake to wire them to 12 volts. Your dark hour (evening/night) use will dictate how big a battery bank you need. If you buy small now, you'll be replacing gear soon.

No. This controller is only intended to be used with panels outputting 17-22volts. A panel intended for a 24V system will be at a higher voltage than 17-22.

I am running 10 solar panels at 1 amp each and are feeding 4 marine deep cycle batteries which feed my N-Power 5000 watt inverter. All are connected together and charging while the inverter is running. The extra voltage from the charge controller/panels helps keep the inverter from shutting down due to low voltage.

will this charger work with a 60w 12 volt solar panel array?

meethead

(read all my Q&A)

March 13, 2011

Answers

To answer your question; let's first look at what you need to EXACTLY handle a 60 watt system.

The formula to start with is:

Watts = Volts x Amps.

Since we are looking for the size of controller needed, rated in Amps, we modify the formula thus:

Amps = Watts/Volts.

We now simply plug the values we know into the formula and solve:

60 watt system at 12 volts, so

Amps = 60/12
Amps = 5.0

This means that you only need a controller rated at 5.0 amps to handle your system. A 30 amp unit will handle six banks of solar units the size of the one you are installing presently. If you have plans on installing four or five banks more anytime soon, this unit is for you. If this is the final installation, get a controller more closely rated to your need.

Do multiple panels need to be hooked "in line" to the controller or can I land multiple panels at controller terminals?

Details:

I have 2ea. 30 watt panels "in line" through the factory pig-tail running to the 30amp controller. I am adding 1ea 190 watt panel. Can I land the wires direct to the controller array terminal (stack them on the terminal screw) or do they all need to be hooked "in line"?

It is reccommended and performs better if the wires are spliced and hooked in line rather than stacking them on the terminals.

If all of your panels are wired in parallel, you can bring additional + and - leads directly to the back of the charge controller. The screws on the unit are not very long, so you may have trouble fitting more than two ring terminals on each lead. It's more cost effective to connect all your panels up a near the panels, however, and simply run a single set of conductors to the back of the charge controller.

This NPower Digital Charge Controller is used to link solar panels together. It stabilizes incoming voltage to prevent 12V batteries from overcharge and discharge. It will handle up to 450 Watts solar power (or wind power). More than one system may be connected to batteries. To get 60 amps of charging current would require 900 watts of power.

NPower Digital Charge Controller - 30 Amp 5 5 3 3

30A controller This little controller does exactly what it claims without fault. I have it connected to a secondary solar array of 2 205W panels, feeding 8 6v deep cycle golf cart (T-105) type batteries wired to 12v. It is a solid, but less costly version of simple 'brand name' controller for a simple system. The main systyem for the house is 1640w in parallel 820w arrays, two 30A MPPT controllers, parallel banks of 12 T105s (24 total) wired to 24v, into an outback VFX3524 sine wave inverter. This setup is protected with DC circuit breakers and lightning arrestors, and monitored with a trimetric and outback 'mate'. This system has worked great for a year and a half and counting. The secondary setup (with this controller) is to power a chest freezer, lights, and a couple of receptacles in the solar shed, so I decided to forego alot of the expense I had in the house system. I fused all points instead of using breakers and dedicated boxes. It's been in service about 4 months so far (as of Jan 2012), and works perfectly. We're offgrid, and I did the install after alot of research. I'd recommend this controller to anyone who wants a cost effective system and doesn't need MPPT capabilities. January 9, 2012

EXCELLENT Charge Controller! I just bought this charge controller along with 10 of the 15 Watt solar panels and this controller is awesome. Not only is it very well built, with a large heat sink on the backside, it provides GREAT status indications of everything going on with your batteries and solar panels! I highly recommend this controller if your are running a solar panel array of more than seven 15 watt panels or any of the other high output panels that go over 100 watts! January 9, 2012

Works as advertised Purchased this unit as a charge controller for my solar system at a remote cabin. It is spliced in between a Sharp 80W polycrystaline solar panel and a bank of three deep-cycle marine batteries. While this unit isn't as feature-packed and fancy as some of the more expensive charge controllers out there, it was simple to hook up and does exactly what it says it will do. It gives you a rough idea of battery charge, status indicators to let you know whether it's in bulk-charge or float-charge mode, and a switch to see voltage and current out of the solar panel. This controller was utilizing the full rated current output of my solar panel (4.7A DC) on a clear sunny day, meaning I can replenish four hours of having a 13W CFL on with about one hour of solar charge time.
